Question 1 of 91
For telemetry data push, data can be transferred between devices and collectors using the TLS protocol. TLS must be configured for data encryption if data is pushed based on gRPC.
    Correct Answer: A

Question 2 of 91
In 6PE and 6VPE networking, no VPN instance needs to be created on PEs.
    Correct Answer: B

    In 6PE and 6VPE networking, VPN instances typically need to be created on PEs (Provider Edge routers). For 6VPE (IPv6 VPN Provider Edge), VPN instances are necessary to isolate and manage the IPv6 VPN traffic. These instances, known as Virtual Routing and Forwarding (VRF) tables, are used to store and process the routes for different VPNs. Therefore, the statement that no VPN instance needs to be created on PEs is false.

By default, the domain ID of an OSPF process is the same as the process ID. You can run the domain-id command in the OSPF process view to change a domain ID.
    Correct Answer: B

    By default, the domain ID of an OSPF process is null, not the same as the process ID. You need to explicitly set a domain ID using the domain-id command in the OSPF process view if you want to assign a specific domain ID.
